Can you hear sound in space?

To answer this question, you first need to understand how sound travels on Earth. In very basic terms, sound travels from the source of the sound to our ears by vibrating air molecules. Sound waves need a medium to travel through. Space is a mostly empty vacuum, so there's no medium for sounds to travel through. In summary, no, you can't hear sound in space like we can on Earth.

However, scientists use a process called sonification to convert the different waves found in space into sounds.
